Z Housing flange, C-type, on both sides
Input-side designs
K4 Adapter unit with plug-in shaft connectionaccording to:- Motor size and mounting position or- Flange size and shaft diameter (additional data required)
Example:
SC 50 - (basic gear unit = SCAZ50)
The series currently comprises three gear unit sizes.
Worm gear units are available in a single-stage version.
Worm and wheel sets with CAVEX gearing
The concave-profile cylindrical worm with its enveloping worm wheel is very much different to conventional designs. The worm threads have a concave profile instead of an involute or convex one.
The concave-profile teeth are subject to only low specific tooth pressure. The retention of a separating oil film between the tooth flanks is facilitated in particular, as the hollow flanks are in con-tact with convex mating flanks. Therefore, profile contact is much more favorable than in conventional gear teeth systems.
The concave-profile teeth provide a particularly favorable posi-tion for the instantaneous axes, which extend mainly at right an-gles to the sliding direction. This assists the build-up of lubricat-ing pressure, i.e. the generation of an oil film between the tooth flanks.
The tooth flanks on new gear units will not yet be fully smoothed, meaning that the friction angle will be greater and efficiency lower during initial operation. The smaller the lead angle or, in other words, the higher the transmission ratio, the more pro-nounced the effect. The run-in procedure should take approxi-mately 24 to 30 hours of operation at full load.
Starting efficiency is never as great as the efficiency at operating speed. This fact should be taken into account when starting a machine at full load, depending on the starting characteristics of the motor.
Notice: In respect of torque driving back from the output shaft, please take into account the reduced gear tooth efficiency η ' = 2 - 1/η , particularly with high transmission ratios of the worm gear stage (η = efficiency with driving worm).

Modular system
SC = Basic gear unit with housing flanges (C-type)
* These modules are mounted at the factory prior to delivery, in accordance with the order.** These modules are not mounted prior to delivery in order to provide greater flexibility during installation.
■ Use
MOTOX worm gear units are characterized by high throughput in a very small space and a high transmission ratio in a single stage. Thanks to their compact design, worm gear units are an ideal solution when installation space is at a premium and they offer a range of mounting options due to their flange, foot, and torque-arm housing designs.
Output shafts are available in different versions and diameters, as solid or hollow shafts. The gear unit housings, made from die-cast aluminum with good thermal conductivity, are strong and absorb vibrations.

The selection tables show the most common variants and combinations. Other combinations can be selected using our MOTOX Configurator or made available on request.
At an identical power and output speed, priority is given in the selection tables to 4-pole geared motors.
At the available transmission ratios, they cover the majority of output speeds.
Due to their prevalence, 4-pole geared motors are easily avail-able, with short delivery times and at a low cost. They also fea-ture a favorable size / power ratio.
